How much is the big range hood used in the hotel kitchen? Looks like iron!

4-72 centrifugal fans should be selected for good smoke exhaust effect in hotel kitchens, because they have high pressure head and large air volume, so the smoke exhaust effect is good. If you choose axial flow fan or exhaust fan, the smoke exhaust effect is not good, because the pressure head of this machine is too small, and the system can not exhaust smoke with a little resistance. This is not good for the overall environment of the kitchen, especially in summer, when the oil fume can't be discharged, the chef will have a problem! The price of centrifugal fan is around 1000-2000. If axial flow fan or exhaust fan is used, the price is around 700. However, from the perspective of use effect and long-term planning, it is recommended to choose centrifugal fans.
